YexSensor YEX-PH-P100 Pen Type Acidity Tester: Portable pH Measurement for Field and Laboratory Water Testing

pH is one of the most frequently checked water quality parameters in aquaculture, environmental monitoring, process water and laboratory testing. YexSensor YEX-PH-P100 Pen Type Acidity Tester provides a compact tool for quick pH and temperature measurement, helping users verify water condition directly at the sampling point.

Core Technical Advantages: Portable pH Testing, Calibration Support and Practical Field Use

pH and Temperature Display

The tester displays pH and temperature values at the same time, giving operators a clearer reference when evaluating sample condition and measurement stability.

Three-Point Calibration Workflow

YEX-PH-P100 supports calibration display values of 4.0, 6.9 and 9.2 at 25 deg C, covering common acidic, neutral and alkaline buffer references for routine pH testing.

Clear Error and Over-Range Prompts

When the measured value is outside the valid range, the meter provides display prompts to help users identify invalid measurement conditions, poor electrode contact or electrode aging.

Portable Battery-Powered Design

The instrument uses four 1.5 V batteries and a pen-type body, making it suitable for daily sampling work, field visits and laboratory spot checks.

Operation and Maintenance Guide

Measurement Preparation

Remove the electrode protection cap, rinse the pH composite electrode with pure water or distilled water, dry it gently and immerse the electrode in the sample. Wait for the pH value to stabilize before recording.

Electrode Storage

The pH composite electrode should be kept moist. If the electrode has dried after long storage, soak it in suitable KCL solution or electrode soaking solution before use.

Cleaning and Protection

The sensitive glass bulb at the front end of the pH electrode must not touch hard objects. Clean the electrode with pure water before and after measurement, especially after viscous samples.
